Abstract

The invention provides a silver-copper alloy material for manufacturing a commutator copper sheet. The silver-copper alloy material comprises Ag, Pt, Cu and Mg metal materials with the weight ratio of (0.2-2): (0.1-0.2): (8-10): (0.2-0.3), the silver-copper alloy material is prepared by smelting Ag, Pt, Cu and Mg raw materials through a vacuum induction smelting furnace to obtain an AgPtCuMg alloy material, then the AgPtCuMg alloy material is subjected to internal oxidation reaction treatment, and the AgPtCuMg alloy material and an oxygen-free copper base material are rolled into an alloy strip. The silver-copper alloy material for manufacturing the commutator copper sheet, provided by the invention, effectively meets the comprehensive requirements for high hardness and wear resistance, enhancement of environmental erosion resistance, improvement of electric contact characteristics, prolonging of service life and the like.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a silver-copper alloy material used for making commutator copper sheets. Background technique [0002] The surface of electrical contact materials is easily affected by the surrounding environment, resulting in poor contact and reduced equipment reliability. The common corrosion failure media of electrical contact materials mainly include dust and atmospheric corrosive media. my country is a dusty country, and the formation of dust and contact failure will also directly affect the composition of dust, which is very complicated. Dust contains about 80% (by weight) of inorganic matter, 20% of organic matter, and a certain amount of water-soluble salts in the inorganic matter. When the dust particles are attached to the surface of the electrical contact material, in the atmospheric environment, it is very easy to absorb the water molecules in the atmosphere, and the water-solub...
